Epoxy nanocomposites as matrices for aramid fiber‐reinforced plastics

et al. 2017

Rheological and mechanical properties of nanofilled epoxy resin were studied, including adhesion to aramid fibers and strength of impregnated aramid strands. Light scattering and rheological measurements data imply that nanodiamonds (NDs) and multiwall carbon nanotubes form stable nanosized agglomerates in epoxy resin, whereas for epoxy‐organomodified montmorillonite systems, individual clay platelets orientation might be present. Also, according to the rheology of these systems, formation of the networks of epoxy molecules adsorbed on the NDs particle surface is suggested. Increase in the viscosity of the epoxy oligomers due to the nanoparticles incorporation results in the worsening of the impregnation of the aramid fibers by these formulations. However, enhanced adhesion properties could be obtained when using nanofillers, with a maximum at 1–2 wt% of nanofillers. A 25–35% growth of the pull‐out adhesion strength is also achieved. Increased cohesive strength and decreased residual stresses are supposed to be the reasons of adhesion strength decrease according to the literature. Adhesion strength increase was accompanied by a 10% enhancement of the strength of impregnated aramid strands. Moreover, a notable effect—up to a fourfold increase—was observed for the impact toughness of epoxy‐nanofillers samples. POLYM. COMPOS., 39:E2167–E2174, 2018. © 2017 Society of Plastics Engineers

“…Thus, the small solubility of polyisobutylene in the polymethylpentene medium cannot cause a sharp decrease in viscosity, as the viscosity of solutions is to obey the rule of logarithmic additivity and cannot be lower than the viscosity of both components [33] (in addition, if the reason for the decrease in blend viscosity was the PIB solubility in PMP, the viscosity of the blend based on the least-viscous B15 would be lower than that of other blends). The low viscosity of the blends may be due to wall slip [34,35], which, however, is unlikely due to the very high adhesion of polyisobutylene to the steel surface (e.g., these polyisobutylenes are the basis of pressure-sensitive adhesives [36,37]). Another explanation may lie in interlayer slip [38][39][40] due to the low adhesion of polyisobutylene to PMP.…”

A series of microfiltration membranes were fabricated by the extraction of polyisobutylene (PIB) from its immiscible blends with polymethylpentene (PMP). Three PIB with different molecular weight of 7.5 × 104 (Oppanol B15), 34 × 104 (Oppanol B50) and 110 × 104 (Oppanol B100) g/mol, respectively, were used to evaluate the effect of molecular weight on the porous structure and transport properties of resulting PMP-based membranes. To mimic the conditions of 3D printing, the flat-sheet membranes were fabricated by means of melting of mixtures of various PMP and PIB concentrations through the hot rolls at 240 ∘ C followed by a quick cooling. The rheology study of individual components and blends at 240 ∘ C revealed that PIB B50 possessed the most close flow curve to the pure PMP, and their blends demonstrated the lowest viscosity comparing to the compositions made of PIB with other molecular weights (B15 or B100). SEM images of the cross-section PMP membranes after PIB extraction (PMP/PIB = 55/45) showed that the use of PIB B50 allowed obtaining the sponge-like porous structure, whereas the slit-shaped pores were found in the case of PIB B15 and PIB B100. Additionally, PMP/B50 blends demonstrated the optimum combinations of mechanical properties (str = 9.1 MPa, E = 0.20 GPa), adhesion to steel (adh = 0.8 kPa) and retention performance (R240 nm = 99%, R38 nm = 39%). The resulting membranes were non- or low-permeable for water if the concentration of PIB B50 in the initial blends was 40 wt.% or lower. The optimal filtration performance was observed in the case of PMP/B50 blends with a ratio of 55/45 (Pwater = 1.9 kg/m2hbar, R240 nm = 99%, R38 nm = 39%) and 50/50 (Pwater = 1100 kg/m2hbar, R240 nm = 91%, R38 nm = 36%).

“…Many polymers are used as bases, the most common being ethylene-vinyl acetate, ethylene-acrylate, or ethylene-acrylic acid copolymers [ 34 , 35 , 36 , 37 ], different polyacrylates [ 38 , 39 ], polyisoprene [ 40 ], polyisobutylene [ 41 ], polyethylene [ 42 ], polyvinyl acetate [ 43 ], polylactide [ 44 ], polyamide [ 45 ], polyurethane [ 46 , 47 , 48 ], and polyester [ 49 ]. The polymer base represents more than half of the composition of adhesives and is responsible for their strength, elasticity, viscosity, and adhesion.…”

Hot-Melt and Pressure-Sensitive Adhesives Based on Styrene-Isoprene-Styrene Triblock Copolymer, Asphaltene/Resin Blend and Naphthenic Oil

et al. 2022

Asphaltene/resin blend (ARB) extracted from heavy crude oil was used to modify poly(styrene-block-isoprene-block-styrene) (SIS) to make it an adhesive. There were prepared double and triple mixtures containing 10–60% SIS, 10–40% ARB, and 10–50% naphthenic oil used as an additional plasticizer. The viscoelasticity of the mixtures at 25 °C and 120 °C was studied, their flow curves were obtained, and the temperature dependences of the loss tangent and the components of the complex modulus were measured. In addition, the mixtures were used as hot-melt adhesives (HMAs) and pressure-sensitive adhesives (PSAs) in the shear, peel, and pull-off tests of the adhesive bonds that they formed with steel. Both naphthenic oil and ARB act as plasticizers for SIS and make it sticky. However, only the combined use of ARB and the oil allows for achieving the best set of adhesive properties of the SIS-based mixture. High-quality HMA requires low oil content (optimal SIS/ARB/oil ratio is 50/40/10, pull-off adhesion strength (τt) of 1990 kPa), whereas a lot of the oil is needed to give SIS characteristics of a PSA (SIS/ARB/oil is 20/40/40, τt of 100 kPa). At the same time, the resulting PSA can be used as a hot-melt pressure-sensitive adhesive (HMPSA) that has many times lower viscosity than HMA (13.9 Pa·s versus 2640 Pa·s at 120 °C and 1 s−1) but provides a less strong adhesive bond (τt of 960 kPa).
